Description
Bardia Nabavi leads a ten-author team reporting in 2026 a new route to strong optical nonreciprocity, where light behaves differently depending on its direction of travel. Many photonics tools need that one-way effect in the infrared, yet few materials deliver it strongly. Magnetic Weyl semimetals helped, though choices stayed narrow.
Nabavi and colleagues instead doped cadmium arsenide, a Dirac semimetal, with manganese. The magnetic atoms ordered together, split the material's cone-shaped energy bands, and produced magnetic Weyl cones with a strong one-way response. Changing the doping level or applying a magnetic field tuned the effect. The result offers materials designers a fresh platform for infrared devices.
